New book: "Gregorian Strategy", has anyone tried it?

I came accross a new BJ strategy book today in the bookstore,
"Gregorian Strategy for Multiple Deck Blackjack". Supposedly the 1st
book that takes into account modern day casino's and multiple deck
games. His theory is that standard "basic strategy" is outdated since
it was created 60 yrs ago and based on single deck simulations. Author
claims his methods give 1% advantage. I live in Florida, looking to
try it next time in LV. May try it sooner on gambling boats out of
Tampa that go out to int'l waters for 4 hrs of play. If anyone has
tried, please share your results..............
